#10 x 7/8-14 (#10)Radius O-Ring Fitting Black

The #10 x 7/8-14 Radius O-Ring Fitting Black from FRAGOLA is a precision hydraulic and pneumatic adapter designed for high-performance fluid systems. This straight adapter connects two #10 AN (Army-Navy) male ports, making it essential for custom fuel, oil, coolant, and brake line installations in racing, off-road, and automotive applications. The O-Ring design eliminates the need for tapered thread sealants, providing a cleaner, more reliable seal that resists vibration-induced leakage in demanding environments.

Constructed from aluminum and finished in black anodize, this fitting delivers lightweight durability with superior corrosion resistance. The radius O-Ring design accommodates JIC or O-Ring face seal (ORFS) connections, and the precision machining ensures concentricity and leak-free performance under pressure. Black anodizing not only enhances aesthetic appeal but also provides an additional protective layer against oxidation and chemical exposure, critical in engine bays and exposed mounting locations. The compact 1 x 1 x 1.5-inch dimensions allow integration into tight spaces without compromising flow or system integrity.

Professional builders, fabricators, and motorsports enthusiasts rely on FRAGOLA adapters for custom plumbing systems where reliability is non-negotiable. The straight configuration works in tandem with banjo fittings, 90-degree elbows, and tee junctions to create modular, repairable fluid systems. Compatible with systems operating from fuel injection and turbocharger supply lines to custom cooling circuits, this adapter is buy-it-for-life hardware that fits seamlessly into both street and competition builds.
